CARRIER FOR SPARE DISK WHEELS.

Application filed. August 1, 1922. Serial No. 578,901.

My invention relates to an improved carrier for spare disk wheels. a

The leading object of my invention 1s t0 provide a simple, cheap and efficient device 6 for carrying two spare disk wheels on a motor car.

Another object of my invention is to provide a carrier for spare disk wheels which may be readily andquickly changed so as 10 to carry either one or two spare wheels.

Another object of my invention is to provide a carrier capable of carrying two spare disk wheels which utilizes the principal parts of a single whee1 carrier,.so that the S111- gle wheel carrier can be very quickly and conveniently converted into a dual wheel carrier.

Further objects, and objects relating to details and economies of operation and construction, will definitely appear from the detailed description to follow. In one n stance, I accomplish the objects of my 1nvention by the devices and means set forth in the following specification. My invention is clearly defined and pointed out in the appended claims. A structure constituting a preferred embodiment of my lnvention is illustrated in the accompanymg drawings,

forming a part of this specification, in which:

Fig. 1 is a view in side elevation of a motor car equipped with my carrier, the carrier and disk wheels mounted thereon being shown in central vertical section.

Fig. 2 is a fragmentary, sectional view on an enlarged scale, through the dummy hub, one of the supporting studs and portions of two disk wheels mounted on the carrier.

Fig. 3 is a separated plan view of a supporting stud, spacing member and holding nut, and

Fig. 4 is a detail sectional view, taken on line 4L-4 of Fig. 3.

In the drawings, the same reference numerals refer to the same parts throughoutthe several views and the sectional view is taken looking in the direction of the arrows at the ends of the section line.

One type of carrier at present in use for demountabledi-sk wheels consists of a dummy hub having a plurality of studs which pass through holes adjacent the central opening in the wheel disk and receive nuts screwed on said studs and engaging the disk to clamp it to the dummy hub. It is among the purposes of my present invention to provide means which may be added to a disk wheel carrier of the above construction so as to enable it to carry two disk wheels in place of the single wheel heretofore carried. I accomplish the purposes of my invention by providing members screwed on the studs of the dummy hub and each having a body portion provided with surfaces or shoulders opposed to each other and adapted to engage the two disks to be carried, and a threaded pin projecting from such body portion through the outer disk and receiving a nut which clamps the outer disk to the outer shoulder of said member. In cases where the holes in the disks are formed in sockets therein, I propose to provide ball-faced or tapered, opposed shoulders on said members, which shoulders will seat in the sockets of the disks. Each member is preferably provided with an internally threaded socket to receive the stud and an externally threaded pin to receive the nut, both said socket and pin being coaxial with the opposed shoulders.

Referrin to the numbered parts of the accompanying drawings, in which I have lllustrated a dual carrier for disk wheels constituting .one embodiment of my invention, I have shown a dummy hub, 11, connected by the braces, 12, to the motor vehicle, 10. The dummy hub, 11, consists of a plate which carries a plurality of studs, 13, arranged at equal radial distances from the center of the plate. Each stud, 13, consists of a threaded end, 13, extending through an opening in the plate or hub, 11,

an annular flange, 14, which seats against a-corresponding shoulder formed in the hub plate, 11, and a projecting threaded end, 16. The studs areclamped in position in the dummy hub by the nuts, 15, screwed on the ends, 13', and drawing the flanges, 14,-, against the shoulders formed for them on the dummy hub. The disk wheels to be mounted on the carrier each consist of a wheel disk with an annular rib at the center in which a series of sockets are formed which are perforated to permit the passage of the studs. In this case, a disk, 17, is mounted on the carrier with the studs, 16, passing through the openings in the sockets,

18, of the disk, as shown in Fig. 2. A member, 19, having an internally-threaded socket, 27, is screwed on the threaded end, 16, of each stud. This member, 19, has a pair of spaced, opposed, tapered or ball faced shoulders, and 21, and, when the members, 19, are screwed up on the studs, 16, the tapered shoulders, 20, seat in the sockets, 18, and clamp the disk, 17 against the dummy hub, 11. Each of the members, 19, is provided also with a threaded pin, 22, which is coaxial with the socket, 27, and the shoulders, 20 and 21, and extends from that side of the member having the shoulder, 21. A second wheel disk, 23, is placed in reverse position, that is, with the sockets opening toward the first disk and mounted upon the carrier so that said sockets, 24:, seat on the shoulders, 21, of the members, 19, with the threaded pins, 22, extending through the perforations of the sockets, 24.

The second disk is secured in place by the nuts, 25, screwed on the pins, 22, and each having a flange, 26, engaging the metal of the disk at the edges of the perforations through which the pins, 22, pass. 0

It will be observed that this makes a very simple, efiicient and, convenient carrier for two spare disk wheels and one which can be manufactured at a very low cost. The outer wheel, 23, may be easily removed by unscrewing and removing the nuts, 25. This leaves the inner wheel, 17, still clamped upon the carrier. The inner wheel may be removed by unscrewing the members, 19, from the threaded ends, 16, of the studs, 13. The dummy hub, 11, and the studs carried by it may be identical with the dummy hub and studs used in a carrier for single wheels, in which case simple ball-faced nuts are screwedon the studs to clamp the disk on the carrier. My invention has this decided advantage, that a carrier for single wheels may be converted into a carrier for two wheels by substituting the members, 19, and the nuts, 25, for such ball-faced nuts. The result is that, at a very slight additional expense, the capacity of the carrier may be doubled so that it will carry two wheels.

I am aware that the particular carrier construction illustrated in the accompanying drawing may be changed considerably without departing from the spirit of my invention and, therefore, I claim my invention broadly, as indicated by the appended claims.

Having thus described my invegtion, what I claim as new and useful and desire to secure by Letters Patent of the United States, is: s

1. A carrier for spare disk wheels comprising a dummy hub, a plurality of thread: ed studs carried by said hub, members screwed on said studs, each member including a body portion having opposed surfaces adapted to engage a pair of wheel disks mounted on the carrier, each of said body portions being provided with an externallythreaded pin, and nuts screwed on said pins and clamping the outermost wheel disk to said members.

2. A carrier for spare disk wheels of the type described, having a plurality of concave sockets circumferentially arranged around the center of the disk and perforated for the passage of securing studs, comprising the combination of a supporting member, a plurality of studs carried thereby, disk-engaging members screwed on said studs and each provided with a pair of opposed convex surfaces adapted to engage the concave sockets of two oppositely faced disks, each of said disk engaging members having an axially projecting pin and nuts screwed on the pms of sald members and engaging the outermost disk to clamp it in engagement with the corresponding surfaces of the disk engaging members.

3. A spare wheel carrier adapted to carry a plurality of hubless disk Wheels which have in the disks a plurality of apertures for securing studs, comprising a supporting member provided with a dummy hub, an annular series of disk supporting studs carried by the hub and passing through the apertures in one of the disks, a corresponding annular series of spacing members adapted to be fastened on the studs to clamp one of the disks against the dummy hub and at the same time seat a second disk in spaced relation to the first named disk and an annularseries of means carried by the spacing members for securing the second disk thereto. a

4. A combined spacing and securing member for spare disk wheel carriers or the like comprising a cap nut having a main body portion polygonal in cross section and pro vided at its open end with a convex face and at its closed end with a threaded pin in axial extension of the main body portion.

In testimony whereof, I afiix my signature.
